One end of the chain is pivotally connected, and the other end of the chain limits on the mounting plate.
Further, the two sides of the emptiness avoiding hole are equipped with the positioning gusset of downward bending, and the two positioning gussets protrude into described
It is close in tube body and with its inner wall；The two positioning gussets and the emptiness avoiding hole integrated punching form.
Further, the width of the emptiness avoiding hole is greater than the width of the chain.
Further, the mounting plate is equipped with the circular through hole greater than the chain width, and the chain passes through the circle
Shape through-hole, the end of the chain are connected with the second locating part greater than the circular through hole.
Further, the small end of the chain passes through second locating part, and a resilient key passes through the pin of the chain small end
Hole.
Compared with prior art, which has the advantages that
1, tube body can extend into the inside of door from the side of door, and be tightly connected by connecting flange and door lock, mounting plate
The side for being mounted on doorframe can be locked, so that the door closer is embedded into the inside of door, will not influence the overall beautiful of door；
2, it is resetted using compressed spring and realizes and close the door, structure is simple, and tube body is embedded in door, therefore to appearance
It is of less demanding, so low manufacture cost.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model flush type spring device for closing door；
Fig. 2 is the cross-sectional view of the body portion of the utility model flush type spring device for closing door；
Fig. 3 is the structure chart of portion of chain described in the utility model flush type spring device for closing door.
Specific embodiment
The following detailed description will be further explained with reference to the above drawings.
Hereinafter, a variety of specific details are elaborated, in order to provide to the saturating of the concept for constituting described embodiment basis
Thorough understanding.However, it will be apparent to those skilled in the art that described embodiment can be in these no specific details
In some or all situations get off practice.In other cases, well-known processing step is not specifically described.
Embodiment
As shown in Figure 1-3, flush type spring device for closing door, including tube body 1, connecting screw 2, chain 3 and mounting plate 4；It is described
One end of tube body 1 is equipped with the first limiting section 10 of inside bending, and the other end has the second limiting section 11 to be formed that is recessed inwardly, leans on
The end of nearly second limiting section 11 is equipped with connecting flange 5, and the connecting flange 5 is equipped with emptiness avoiding hole；It is set in the tube body 1
There are movable plate 6, limit plate 7 and compressed spring 8, one end of the compressed spring 8 squeezes the limit plate 7 and limits described second
The inside of limiting section 11, the other end squeeze the movable plate 7, and first limiting section 10 limits the movable plate 6.The activity
The center of plate 6 is equipped with threaded hole, and the connecting screw 2 protrudes into the tube body 1, and one end is connect with the threaded hole, the other end
It is pivotally connected with one end of the chain 3, the other end of the chain 3 limits on the mounting plate 4.Tube body 1 can be from the one of door
Side extend into the inside of door, and is tightly connected by connecting flange 5 with door lock, and mounting plate 4 can lock the side for being mounted on doorframe,
So that the door closer is embedded into the inside of door, the overall beautiful of door will not influence；When door is opened, 8 quilt of compressed spring
Compression, at closing time, compressed spring 8 reset, and chain 3 is pulled to retract in tube body 1, realize automatic door-closing；Due to using compression bullet
Spring 8, which resets, to be realized and closes the door, and structure is simple, and tube body is embedded in door, therefore to the of less demanding of appearance, so production
It is at low cost.
Further, the two sides of the emptiness avoiding hole are equipped with the positioning gusset 60 of downward bending, and the two positioning gussets 60 protrude into
It is close in the tube body 1 and with inner wall；The two positioning gussets 60 are formed with the emptiness avoiding hole integrated punching.In connecting flange 5
When being welded on the end of tube body 1, positioning support can be played the role of, convenient for welding.
Further, the width of the emptiness avoiding hole is greater than the width of the chain 3.So that chain 3 is able to rotate, make it possible to drive
Connecting screw 2 rotates, and reaches and connect with threaded hole.
Further, the mounting plate 4 is equipped with the circular through hole greater than 3 width of chain, and the chain passes through described
